Wire gauge size and load capacity ampacity limits

Is this the correct wire gauge and load capacity chart you guys use to figure out what size fuse to use for a particular wire size?

or do you guys go by this chart The American Wire Gauge Table see below?

All depends on the quality of the wire. I went to a local shop last weekend and it was either $17 a foot for this type of 1/0 (forgot name) or $4.50 a foot for some tsunami...i got the tsunami.

the american wire chart is more than likely for household wireing as in solid strand not multi stranded wire

or you can use this

However you would be better off using a fuse size that is the same as your amp fuse instead of the max that the wire can handle
